1. Functions of the muscular system

2. Stabilize joints with their TENDONS (connect muscle to bone) Relaxes and contracts, and provides force to move your body parts In the process, energy is used to do work and heat is produced. This heat helps to keep you body temperature regular. Provides support

11. How the skeletal System is a simple machine A Lever is a rod or plank that pivots around a fixed point. Bones=Rod Joint=Fulcrum Contraction and relaxation of muscles=force needed to move the lever

12. How do muscles work

13. Control: information from the brain through a motor neuron that tells the cell to contract. Muscles need energy…the blood carries energy- rich molecules called glucose. Chemical energy stored in these molecules is released through a process called cellular respiration. This chemical energy is transferred into mechanical energy (movement) and thermal energy (heat). When the supply of energy is used up, the muscle becomes tired and needs to rest.

14. How do muscles work Opposing muscles: Muscles can only pull they can not push.

17. How do muscles change? Using your muscles can make a muscle larger and stronger. Not using your muscles can make a muscle smaller and weaker. These changes are mostly due to a change in the size of the muscle cell.
